Record
- as of
Fixes received: estimated 1
Each fix below rests partly on our inference, not only on the maker's word. By this estimate, the newest firmware we know for this model has them. Not counted in the other numbers on this page.
Basis: The maker lists this model for the CVEs below but doesn't name the fixed firmware for it. The version comes from a CVE record by another organisation or from the maker's download page. The firmware we recorded for this model is on a different version line from the fixed firmware, so we assumed it has the fix because its number or date is later.
Firmware 230426 or later
